Oracle contains the representation of a certain character

In Oracle, use the LIKE operator to check whether a string Contains specific characters. The syntax of the LIKE operator is as follows:

<code>SELECT column_name FROM table_name WHERE column_name LIKE '%character%';</code>

where:

• column_name is the name of the column you want to check.
• table_name is the name of the table from which you want to find data.
• character is the character you are looking for.
• % is a wildcard character, which means that the character can appear anywhere in the string.

Example

Suppose you have a table named customers that contains a table named name of columns. You want to find all customers that contain the letter "a". You can use the following query:

<code>SELECT * FROM customers WHERE name LIKE '%a%';</code>

This query will return all customer records that contain the letter "a" in the name column.

Additional Notes

• To find an exact match, use the =_ operator. For example:

<code>SELECT * FROM customers WHERE name = 'John Smith';</code>

• To find a string that does not contain a specific character, use the NOT LIKE operator. For example:

<code>SELECT * FROM customers WHERE name NOT LIKE '%3%';</code>
